//! # TiKV's Coprocessor Framework
//!
//! A coprocessor framework that allows custom, pluggable coprocessor plugins to
//! execute arbitrary user requests directly on TiKV nodes.
//!
//! *Note: While there currently also exists a different
//! [coprocessor][super::coprocessor] that is designed to execute a defined set
//! of functions on TiKV nodes, this coprocessor framework allows to register
//! "coprocessor plugins" that can execute arbitrary code directly on TiKV
//! nodes. The long-term goal is to fully replace the existing coprocessor with
//! an equivalent plugin for this coprocessor.*
//!
//! ## Background
//!
//! The design of the coprocessor framework follows closely the principles of
//! [HBase's coprocessor][hbase-copr] which in turn is built on the ideas of the
//! coprocessor framework in Google's BigTable.
//!
//! By registering new coprocessor plugins, users are able to extend the
//! functionality of TiKV and run code directly on storage nodes. This usually
//! leads to dramatically increased performance because the CPU of TiKV nodes
//! can be utilized for computation and the amount of data transfer can be
//! reduced.
